PNEUMATIC TIRE.

SPECIFICATION forming part of Letters Patent No. 766,463, dated August2, 1904.

Application filed February 15, 1904. Serial No. 193,669. (No model.)

To It who/11, it may concern:

Be it known thatI HARRY A. PALMER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Pneumatic Tires; and [dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,forming part of this specification.

I\Iy invention relates to pneumatic tires and mechanism for securing thetire-sheath to vehicle-wheels; and it consists substantially inimprovements of the devices embodied in my application for LettersPatent, Serial No. ISLUM, filed November 13, I903, forimprovements invehicle-tires.

The object of this invention is to construct a pneumatic tire-sheathhaving an opening or slit around its inner face, through which accessmay be had to the interior of the sheath, and with reinforcing-strips inthe sides of the inner face thereof, so that belts or rivets havingbroad flat heads bearing against the sides of the tire-sheath may bepassed through holes in the sides of the sheath above thereinforcing-strip therein and through radial flanges on the wheel-rim,so that the sides of the tiresheath can be firmly clamped against theinner faces of the flanges, and thereby secured in place on thewheel-rim, yet can be quickly and readily removed when necessary.

The features of my invention are hereinafter fully set forth anddescribed, and illustrated in the accompanying drawings, in which Figure1 is a transverse section of a pneumatic tire-sheath and wheel-rimembodying my invention. Fig. 2 is a section thereof on the line .11 .rin Fig. 1. Fig. 3 is a view of one of the broad-headed clampingbolts.

In the drawings illustrating my invention, A designates a wheel-telly, Ba metal tire thereon, and C G radial flanges removablysecured to thesides of the wheel-folly, so as to form a channel on the periphery ofthe wheel.

I) is a pneumatic tire-sheath made of the usual outer resilient coveringand inner layers of fabric to reinforce and strengthen the casingsufficiently to resist the pressure of air exerted thereon when theinner tube is in place therein and inliated for use. In the inner faces(Z (I of the sides of this tire-sheath I mold and vulcanize in placetherein reinforcing-strips E E, consisting of rings of wire, wire cord,or other suitable material, and through the sides 1! of the tire-sheathI make bolt or rivet holes F F, in which I insert belts or rivets H,(see Fig. 3,) having, preferably, thin flat oblong heads IL thereon, soas to afford largo bearing-surfaces therefor against the tire-sheath,which belts or rivets pass through holes in the radial flanges C C, sothat the sides of the tire-sheath are firmly secured thereto. It will beseen that I am enabled thus to secure the tire-sheath firmly in thechannel on the rim of the vehicle-wheel and at the same time access canreadily be had to the interior of the sheath either by removing thebolts H on one side or by removing one of the flange-rings C from thewheel.

Having thus shown and described my invention, so as to enable others toconstruct and utilize the same, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. The combination in a pneumatic vehicletire, of a wheel, removablechannel-flanges on the wheel-rim, a tire-sheaf open on its inner faceadapted to fit into the channel on the wheel-rim, reinforcing-strips inthe sides of the tire-sheath, and means for securing the sides of thetire to the inner faces of the channel-flanges, substantially as setforth.

2. The combination in a pneumatic vehicletire, of a wheel, removablechannel-flanges secured to the sides of the rim of said wheel, atire-sheath open on its inner face and adapted to fit into the channelon the wheel-rim, reinforcing-strips in the sides of the tire-sheath tothe inner faces of the channel-flanges, subnear the inner face thereofand bolts or rivets stantially as set forth.
